Course Description


The certification of acquired data is a very critical aspect of wireline and Logging-while-Drilling (LWD) logging and is performed through the observation of key quality indicators. The main objective of this GLOMACS training course is to make you aware of these quality indicators as well as the different techniques to solve commonly found issues at the wellsite.

This GLOMACS training course will explore the tools response explained from their physical principles as well as their relationship with the rock and fluid properties, most common open hole logging technologies will be covered explaining their main applications and limitations. Basic petrophysical interpretation will be discussed with numerous examples and exercises in order to complement your knowledge to be able to perform a proper log QA/QC analysis.

This GLOMACS training course will feature:

  • Explanation of petrophysical concepts and techniques.
  • Discussions on tools physical principles, applications and QA/QC
  • Tool limitations on different borehole environments.
  • Metrology concepts and applications on wireline and LWD logs
  • Multiple log quality control exercises


By the end of this GLOMACS training course, participants will be able to:

  • Understand the physical principles of wireline and Logging-while-Drilling (LWD) logging tools
  • Apply quality control techniques to validate logging data
  • Know the main applications and limitations of the different tool readings
  • Perform a complete log quality control in a set of logs
  • Perform a basic log interpretation

Training Methodology

This GLOMACS training course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented, the sessions will include visual, auditory and kinesthetic elements to cover the three different learning modalities.

The daily sessions will be highly interactive and participative. This involves regular discussion of applications as well as hands-on exercises that will be solved manually and/or using Microsoft Excel. 

Organisational Impact

The organization will benefit because:

  • Having their personnel trained on log interpretation will help reduce human mistakes and improve efficiency
  • Their personnel will be able to better assess data quality and integrity
  • Their personnel motivation will increase as they understand better some critical data needed for their daily job

Personal Impact

Attendees will gain by participation in this GLOMACS training seminar as a result of:

  • Obtaining a full understanding of logging tools principles and applications
  • Learning the principles and key indicators for log quality assurance and quality control
  • Learning basic and advanced methods and techniques for log interpretation


This GLOMACS training course is suitable to a wide range of professionals but will greatly benefit:

  • Engineers in exploration and production departments
  • Geologists, geophysicist and petrophysicist
  • Petroleum, reservoir and drilling engineers
  • In general, all other oil & gas industry professionals who are involved in logging data QA/QC and validation
